Marijuana possession is still a federal crime, but law enforcement and prosecution has been extremely confusing in many states -- including Michigan -- which have legalized the use of marijuana to varying degrees.

There’s been significant movement at the state capitol regarding medical marijuana recently. The week before last, the Michigan Supreme Court ruled the state’s pot law does not allow dispensaries. But late last week, State Representative Mike Callton of Nashville announced he’ll introduce a bill that would allow businesses to dispense cannabis.

Stuart Dunnings Jr. is Ingham County prosecutor and among the many legal officials and police who’ve been frustrated by the vagaries of Michigan’s medical marijuana law. Robin Schneider is a Lansing resident and a legislative liaison for the National Patients’ Rights Association. They both help clear some of the haze around Michigan's medical marijuana regulations.
